Silicon Carbide

Silicon Carbide Overview

Family Overview

Silicon Carbides (SiC) exhibit characteristically high hardness, wear resistance, corrosion resistance, and strength — even at high temperatures. CoorsTek has engineered a variety of silicon carbide processes and compositions which deliver properties and features optimized for specific application requirements including:

Electrical resistivity: Careful manufacturing control can “tune” the volumetric resistivity.

Lubrication: Certain formulations have graphite embedded into the grain structure for lubrication in exchange for slightly lower flexural strength.

CoorsTek UltraClean™ Siliconized Silicon Carbide (Si:SiC) is a unique silicon carbide in which metallic silicon (Si) infiltrates spaces between the grains ─ allowing extremely tight tolerances even for large parts. Siliconized silicon carbide is ideal for high-stress applications which require great mechanical strength along with excellent corrosion and wear resistance.
